A radical project has been proposed to fully electrify nearly 120 miles of railway between Dunblane and Aberdeen - which could see Perth and Kinross passengers facing seven years of disruption.
Network Rail has submitted plans to the six affiliated councils which would see the installation of overhead power lines on the vast majority of the existing Aberdeen to Central Belt - A2CB - track, meaning a number of historic bridges will be demolished.
The national railway body said the project will “deliver significant environmental benefits” and “enhance the infrastructure” for years to come.
